Critical: Major VRAM memory leak/performance degradation after 1–3 matches

After I play 2-3 rounds of the game, the FPS drops from 80 to 30.

I have already set the graphics quality to the lowest, but this problem still occurs.

The game was upgraded to version 1.1.1.5, but this problem has not been resolved.

My computer configuration is：

CPU:5600

GPU:VEGA64

RAM:16G

STEAM

At the same time, DX sometimes also reports errors.
